Opened product and serving
Apply instructions to the actual whole, sliced or rice-containing product.

Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
Reported evidence

What it is Filled
Funazushi is a traditional Japanese narezushi associated with Shiga Prefecture, made by salting crucian carp and fermenting it with cooked rice to produce a sour, strongly aromatic preserved fish.
In scope
- Funazushi identity and boundaries within the broader narezushi family
- Fish identity, roe presence, rice, salt and additional ingredients
- Batch-specific salting and rice-fermentation history
- Measured maturation indicators and sensory condition
- Product form, storage history and evidence supporting consumption decisions
Out of scope
- Crucian carp taxonomy, ecology and fisheries management
- Narezushi varieties made from other fish
- Fermentation microorganisms as independently modelled organisms
- Production equipment and general food-factory operations
- Recipes for complete dishes incorporating funazushi
- Regional festivals and cultural institutions as independent entities
Why it exists Filled
Enable an agent to recognise funazushi, assess the documented condition of a particular batch, and determine appropriate handling and culinary use.
Distinguishing features Filled
- Identify the fish as funa, or crucian carp, rather than treating every rice-fermented fish as funazushi.
- Look for a history of salting followed by fermentation with rice; a fish-and-rice presentation alone does not establish identity.
- Distinguish fermentation-based preparation from sushi assembled with vinegar-seasoned rice.
- Record Shiga or Lake Biwa associations separately from the actual origin of the fish and manufacturing location.
- Treat roe presence, retained rice and whole versus sliced presentation as recorded variants whose necessity for identity requires evidence.
What robots and AI may and may not do Filled
Must not
- Advise home fermentation of fish without stressing that food safety guidance must be followed.
- Mislabel the origin, species or production method of funazushi for sale.
- Mock the food or the community that keeps the tradition.
- Promote catching wild crucian carp where stocks are protected or restricted.
Only with a human decision
- Recalling a batch after a food safety finding.
May
- Describe funazushi, its history in Shiga and its place in Japanese food culture.
- Report producer, ingredients and storage instructions from a product label.
- Explain that it is a fermented product with a strong aroma that some find hard to eat.
Moral aspects Filled
- Funazushi is a living tradition of Lake Biwa communities and depends on healthy fish stocks.
- Fermented fish carries real food safety risks if made badly.
Who is affected
- Consumers
- Lake Biwa producers and fishers
- Wild fish populations
Owners Filled
Steward
The producer; local food safety authorities oversee commercial products.
